Issues to be aware of
If you're considering trying probiotics, there are a few issues you need to be aware of.
Probiotics are generally classed as food rather than medicine, which means they don't go through the rigorous testing medicines do.
Because of the way probiotics are regulated, we can't always be sure that:
- the product actually contains the bacteria stated on the food label
- the product contains enough bacteria to have an effect
- the bacteria are able to survive long enough to reach your gut
There are many different types of probiotics that may have different effects on the body, and little is known about which types are best.
You may find a particular type of probiotic helps with one problem. But this doesn't mean it'll help other problems, or that other types of probiotic will work just as well.
And there's likely to be a huge difference between the pharmaceutical-grade probiotics that show promise in clinical trials and the yoghurts and supplements sold in shops.
